Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Inductance** | 0.33 µH | | **Tolerance** | ±20% | | **Case Size (Metric)** | 2016 (2.0mm x 1.6mm) | | **Height (Max)** | 1.0 mm | | **DC Resistance (Max)** | 21 mΩ | | **Rated Current (Isat)** | 5.2 A (based on inductance change) | | **Rated Current (Itemp)** | 4.0 A (based on temperature rise) | | **Operating Temp** | -40°C to +125°C | --- ### 2. Core Features and Construction * **Metal Alloy Core:** Unlike traditional ferrite inductors, this part uses a metal powder core. This allows for **Soft Saturation** characteristics, meaning the inductance drops gradually as current increases rather than dropping off sharply. * **Magnetic Shielding:** The construction is naturally shielded, which minimizes Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Low Profile:** With a maximum height of 1.0mm, it is ideal for ultra-thin consumer electronics like smartphones and wearables. * **High Current Density:** It handles significantly higher current than standard multilayer inductors of the same size. --- ### 3. Typical Applications The DFE201610P-R33M is primarily designed for **DC-DC conversion** in portable power management modules. * **Smartphones & Tablets:** Used in CPU/GPU power rails where space is tight and high efficiency is required. * **Wearable Tech:** Ideal for smartwatches and fitness trackers due to the small 2016 footprint. * **SSD/Storage:** Power regulation for high-speed data drives. * **IoT Modules:** Compact wireless sensors requiring efficient power management. --- ### 4.
